DTC REPRODUCTION PROCEDURE

1.

DTC REPRODUCTION PROCEDURE 

With CONSULT-III

1.

Turn the ignition switch ON.

CAUTION:

Never start the engine.

2.

Check the tire pressure for all wheels and adjust to the specified value. Refer to 

WT-80, "Tire Air Pres-

sure"

. 

3.

Perform “AIR PRESSURE MONITOR” self-diagnosis.

Is DTC “C1716”, “C1717”, “C1718”, or “C1719” detected?

YES

>> Perform trouble diagnosis. Refer to 

WT-20, "Diagnosis Procedure"

. 

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005549610

1.

CHECK TIRE PRESSURE SIGNAL

With CONSULT-III

1.

Check and adjust the tire pressure for all wheels. Refer to 

WT-80, "Tire Air Pressure"

. 

2.

Perform transmitter ID registration for all wheels. Refer to 

WT-7, "ID REGISTRATION PROCEDURE :

Transmitter ID Registration Procedure"

. 

3.

Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.

4.

Stop the vehicle and within 15 minutes select “DATA MONITOR” of “AIR PRESSURE MONITOR” and
read the tire pressure for all wheels.

5.

Check that “DATA MONITOR” displays a tire pressure of 438.60 kPa (4.47 kg/cm

2

, 63.60 psi).

Is the inspection result normal?
